Abstract

Clinical and morphologic features are described in 27 patients with prosthetic valve endocarditis. The interval from valve replacement to onset of symptoms of prosthetic valve endocarditis was less than 2 months in 10 patients, longer than 2 months but less than 6 months in seven patients, and longer than 6 months in 10 patients. The most frequent infecting organism was Staphylococcus (11 patients). In nearly all patients, infection spread behind the site of attachment of the valve prosthesis and resulted in valve ring abscesses. Twenty-three of the 28 infected prostheses were partially or almost completely detached, and in 15 patients the infection destroyed the entire valve anulus, burrowing to adjacent structures in six. Despite prolonged bactericidal antibiotic therapy, bacterial cultures of prosthetic valves removed at operation or autopsy were positive in 14 patients. Standard valve replacement was attempted in nine patients. All were hospital survivors, but two of these patients evidenced rapid postoperative valve dehiscence and required a complex surgical procedure at reoperation. The 14 other surgically treated patients had almost complete destruction of the annular root, and surgical repair was achieved by complex sur...Continue Reading

CRISPR & Staphylococcus

CRISPR-Cas system enables the editing of genes to create or correct mutations. Staphylococci are associated with life-threatening infections in hospitals, as well as the community. Here is the latest research on how CRISPR-Cas system can be used for treatment of Staphylococcal infections.
